The tourist was airlifted to Wilcox Memorial Hospital Sunday afternoon where she remains in critical condition .

Kauai police shutdown access to the popular trail at Ke'e Beach Monday and Tuesday while they search for the man believed to have thrown the tourist from the trail.

Police are searching for 37-year-old Justin Wynn Klein on suspicion of attempted murder. Witnesses reported to police that they saw him throw the woman from off the trail that hugs the picturesque Na Pali Coast.

Kauai police escorted hikers out of the area near the start of the popular Kalalau trail, as they search For Klein.

In the windows of businesses nearby, hang posters of Klein, a former Kauai resident, now suspected of attempted murder.

"It's pretty shocking for the island of Kauai," said Lihue resident Joanie Lemi. "It shouldn't be happening on Kauai. This is a place to just come out and relax."

The Japanese woman and a friend had been camping nearby. Debbie, who asked us only to use her first name, met the women over the weekend.

"They were just arm in arm, singing and humming and they were just like happy," Debbie commented. "She just had the happiest smile on her face."

Debbie added that Klein met them on the trial as well and became acquainted with the pair.

"He befriended them when they were here," Debbie added. "They were camping in the beach park and they seemed friendly, and you know, met a lot of people."

Like many people on the island, Debbie is shocked by the alleged violent act.

"You fell safe when you go out hiking and doing things," she said. "Normally if somebody gets injured it's because of an accident, not because of someone deliberately doing something. So I think everybody just wants this guy caught quickly."

Klein is described as a Caucasion man standing 6'1" tall, weighing 200 lbs with brown hair and brown eyes.

He has a Mohawk haircut, was last seen with a mustache and beard and has a tribal tattoo on his left arm.

Police added he is known by the nickname, "The All Mighty", and that he is considered dangerous and should not be approached.
